Description

[0001] Functional contactor and mobile electronic device having same [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a functional contactor and a portable electronic device having the functional contactor, and more particularly, to a functional contactor capable of providing various functions and a portable electronic device having the functional contactor.

[0003] In recent portable electronic devices, various component elements are densely arranged in the interior in accordance with miniaturization and multifunctionalization. Accordingly, a conductive gasket is used between the external housing and the internal circuit board of the portable electronic device to reduce the impact from the outside while simultaneously penetrating into the portable electronic device or reducing electromagnetic waves leaking from the portable electronic device.

In addition, the portable electronic device may have a plurality of antennas for each function in accordance with multifunctionality, and at least a part of them may be an internal antenna and disposed in an external housing of the portable electronic device. Therefore, a conductive contactor is used for electrical contact between the antenna disposed in the external housing and the internal circuit board of the portable electronic device.

In addition, portable electronic devices have recently been increasing in adoption of housings made of metal to improve esthetics and robustness.

As a result, an electrical path can be formed between the housing and the internal circuit board by the conductive gasket or the conductive contactor. In particular, as the metal housing and the circuit board form a loop, The static electricity may flow into the internal circuit board through the conductive gasket or the conductive contactor, and the circuit such as the IC may be damaged.

On the other hand, such a portable electronic device typically uses a charger to charge the battery. Such a charger rectifies an external AC power source to a DC power source and then through a transformer to a low DC power source suitable for a portable electronic device. Here, in order to enhance the electrical insulation of the transformer, a Y-CAP composed of a capacitor is provided at both ends of the transformer.

However, when the Y-CAP does not have the normal characteristics, such as a non-genuine charger, the DC power may not be sufficiently blocked by the Y-CAP, and furthermore, a leakage current may be generated by the AC power source. Can propagate along the ground of the circuit.

Such a leakage current can be transmitted to a conductor that can be contacted with a human body as in an external case of a portable electronic device. As a result, the user can be displeased with a feeling of crushing and, in severe cases, It causes an electric shock accident.

Therefore, it is necessary that a protective element for protecting the user from such luminescence current is provided in the conductive gasket or the conductive contactor connecting the metal housing and the circuit board.

In addition, when the metal housing is used as an antenna, the conductive gasket or the conductive contactor is required to realize a high capacitance because the signal is attenuated when the capacitance is low, and the RF signal is not transmitted smoothly.

Thus, there is a need for a contactor having various functions for protecting a user or a circuit in a portable electronic device as well as a simple electrical contact according to the use of a conductor such as a metal case.

However, in order to implement these various functions, additional component elements are required, and thus, an additional space is required on the circuit board of the portable electronic device, which adversely affects miniaturization.

Particularly, in a portable electronic device, when the metal case and the LCD substrate are connected by the conductive gasket or the conductive contactor, a separate means for mounting the conductive gasket or the conductive contactor and the additional component elements, for example, the FPCB, Because it is needed, not only does it require additional space, but also the cost of production increases.

On the other hand, in the case of integrating the additional component element with the conductive gasket or the conductive contactor, when the conductive gasket or the conductive contactor is formed only on one side, the impact due to the externally applied pressing force concentrates only on a part of the conductive gasket or the conductive contactor do. Therefore, the conductive gasket or the conductive contactor is deformed to cause poor contact with the circuit board or the conductor, and the service life is shortened.

Particularly, when the conductive contactor has a clip shape, since the contact with the conductor is made by the line contact, slip or the like may occur on one side, resulting in poor contact.

Therefore, it is inevitable to develop a contactor capable of achieving stability and miniaturization in contact with a human-accessible conductor and an internal circuit while having a function for protecting a user or an internal circuit.

The present invention may be embodied in many different forms and is not limited to the embodiments described herein. In order to clearly illustrate the present invention, parts not related to the description are omitted, and the same reference numerals are assigned to the same or similar components throughout the specification.

9 and 10, the functional contactor 400, 400 'is a pair of silicone rubber pads 410, 420 where the conductive connection is a pair of silicone rubber pads 410, 420 each having a body 412, 422 And conductive wires 414 and 424, respectively.

The bodies 412 and 422 may be made of silicone rubber. Here, the upper portion of the body 412 may be in surface contact with a conductor 12 such as an antenna or a metal housing, and a lower portion thereof may be electrically connected to the functional element 130. Similarly, the upper portion of the body 422 may be electrically connected to the functional device 130, and the lower portion thereof may be in surface contact with the circuit board 14. [

The conductive wires 414 and 424 may be vertically formed inside the bodies 412 and 422, respectively. These conductive wires 414 and 424 are intended to improve the electrical contact with the conductor 12 or the circuit board 14 (see FIG. 6) while supplementing the elastic force of the bodies 412 and 422.

For example, when the conductive wires 414 and 424 are pressed by the conductor 12 or the circuit board 14, when the upper end is bent downward, the lower end is bent upward, and the conductor 12 is removed , The elasticity of the bodies 412 and 422 can be compensated for by restoring the original vertical state.

11, the functional contactor is a case in which the conductive connection is another type of silicone rubber pad 510, the silicone rubber pad 510 includes a body 512 and a conductive wire 514 .

At this time, if the conductive wire 514 is tilted by the pressing force of the conductor 12 or the circuit board 14, the contact with the conductor 12 or the circuit board 14 becomes excellent, The conductivity of the signal can be improved.

9, the conductive wire 514 is excellent in the conductivity of the communication signal, the elastic restoring force is good, and the long-time use is possible as compared with the vertically formed conductive wires 414 and 424 of FIG. 9 bent to one side by the pressing force of the conductor 12. [ .

12, the functional contactor is a silicone rubber pad 610, which includes a body 612, a conductive layer 614, and a contact portion 616 do.

This conductive layer 614 is intended to improve the electrical contact with the conductor 12 or the circuit board 14 while supplementing the elasticity of the body 612.

For example, when the conductive layer 614 is pressed by the conductor 12 or the circuit board 14, the conductive layer 614 is pressed downward in the vicinity of the central portion thereof, and when the conductor 12 is removed, By restoring to the horizontal state, the elastic force of the body 612 can be compensated. Thus, this conductive layer 614 is electrically connected to the vertically formed conductive wires 414 and 424 of FIG. 9 bent to one side by the pressing force of the conductor 12 or the circuit board 14, or the right- The elastic restoring force is superior to that of the elastic member 514 and can be used for a long period of time.

The contact portion 616 may be formed as a curved projection on the upper side of the body 612. This contact portion 616 can increase the contact area with the conductor 12 or the circuit board 14 by making multiple line or surface contact with the conductor 12 or circuit board 14 such as an antenna or a metal housing have. Accordingly, the silicone rubber pad 610 can improve the conductivity of the communication signal.

The functional contactor as described above may be disposed on the body-contactable conductor 12 and the circuit board 14 in a portable electronic device. Here, the functional contactor may be mounted on the mounting terminal of the circuit board 14. [

The conductive portion 714 may be made of conductive silicone rubber and conductive particles. The conductive portion 714 may be formed by filling a plurality of through holes 713 with a conductive silicone rubber and conductive particles. Here, the conductive silicone rubber has a function of fixing the position of the conductive particles in the through holes 713, and the conductive particles may be regularly or irregularly arranged and disposed in the conductive silicone rubber.

At this time, when the pressure or heat is not externally applied to the conductive particles, the conductive particles are not separated from each other and are not energized. When pressure or heat is externally applied, the conductive particles may contact each other due to shrinkage of the conductive silicone rubber, .

Such a conductive portion 714 can realize electrical contact with the conductor 12 or the circuit board 14 by the conductive particles, and contraction and expansion can be realized by the conductive silicone rubber. Therefore, the conductive part 714 can simultaneously provide electrical contact and elastic restoring force by pressurization.

For example, when the conductive part 714 is pressed by the conductor 12, the conductive silicone rubber shrinks and the conductive particles come into contact with each other, thereby electrically connecting the conductive particles to each other, When the conductor 12 is removed, it can be restored to its original state by the elastic force of the conductive rubber. Therefore, the conductive portion 714 is superior in elastic restoring force as compared with the conductive wires 414, 424, 514 or the conductive layer 614 of Figs. 9 to 12, and is made of the same or similar material as the body 712, Can be reduced, and therefore, can be used for a long period of time.

The contact portion 716 may be formed in a curved shape on both sides of the conductive portion 714. This contact portion 716 can increase the contact area with the conductor 12 or the circuit board 14 by making a plurality of lines or surfaces contact with the conductor 12 or the circuit board 14. [ Thus, the silicone rubber pad 710 can improve the conductivity of the communication signal.
